To all whom it may concern:

Be it known that I, PATRICK J. HARE, a citizen of the United States, andresiding at New York, in the county of N cw York and State of New York,have invented certain new and useful Improvements in Apparatus forExtracting Liquids from Garbage or Offal, of which the following is aspecification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to apparatus for extracting or separating liquidsfrom garbage or offal so that said garbage or ofial may be treated inthe usual manner for any purpose, and the object of the invention is toprovide an apparatus of the class specified which is simple inconstruction, convenient of and effective in operation, and which isalso comparatively inexpensive, and by means of which the said operationof separating liquids from garbage or offal may be quickly, easily andeffectively performed; and with this and other objects in view theinvention consists in a machine or apparatus of the class specified,constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a sectional side view of mycomplete apparatus with part of the construction broken away;

Fig. 2 a sectional plan view on the line 22 of'Fig. 1 with part of theconstruction broken away; and,

Fig. 3 a transverse sectional view on the line 33 of Fig. 1 and lookingbackward and on an enlarged scale.

In the practice of my invention, as shown in the drawing, I provide astrong and substantial main frame consisting of two similar side membersa composed of any suitable material and connected, in the constructionshown, by two transverse bolts, bars or rods a at the opposite ends andnear the bottom thereof and by transverse bars a at the top thereof, butthe side members a of the main frame may be formed and connected in anydesired manner.

The main frame, or the'side members thereof, are provided centrally ofthe top thereof with a raised portion a in which are mounted two rollersb, and said raised portion a of the frame, or the side members thereof,are provided with vertically arranged slots or openings 5 over which aresecured yoke-shaped brackets 5 and mounted in the slots or openings 5are vertically movable bearing blocks 5*, and the rollers 79 areprovided with reduced end portions 5 through which are passed shaft 5the ends of which pass into the bearing blocks 5 Mounted in theyoke-shaped brackets b are threaded sleeves provided at their upper endswith nut-shaped heads 5 and at their lower ends with blocks 5 and passeddownwardly through the threaded sleeves b and screwed into the bearingblocks 5 are rods 0 provided at their upper ends with handle members 0and between the blocks 5 and the bearing blocks If are spiral springs cthrough which the rods 0 pass, and by means of this construction thebearing blocks o and the rollers 12 may be raised and lowered, oradjusted vertically when desired, and the springs a normally serve todepress the rollers 6 as will be understood. The blocks 5 are rotatablewith the sleeves 5 and by turning said sleeves the tension of thesprings 0 may be regulated.

Mounted directly under the rollers b are cylindrical drums d which arehollow in form and which are provided with end members d having hubportions (Z and shafts d are passed through said drums and through theside portions of the main frame, and the end portions d of said drumsare provided with projecting flanges (i The body of the front drum d isprovided with circumferential grooves 03, in the form of constructionshown, and longitudinal grooves d which intersect the grooves d, and atthe points of intersection of these grooves, said drum is provided withapertures (Z and the body of the rear drum cl is provided, in the formof construction shown, with longitudinal slots or openings (Z which arepreferably arranged as shown in Fig. 2 so that the longitudinal slots oropenings in one line will overlap those in another.

The shafts (Z* of the drums (Z are provided at the right side of themachine with gears e and at the left side of the machine with worm gears6 and the gears at the right side of the machine mesh with similar gearse mounted on the shafts b which extend through the bearing blocks 6 atsaid side of the machine.

On the outer side of the left side of the machine is mounted a worm gearshaft having worms f which mesh with the worm gears 0 and the shaft f isprovided centrallywith a ratchet f and the left side frame member a isprovided between the rollers Z) with projecting arms 7" in which ismounted a vertically movable rod f provided at its lower end with a pawlf operated in one direction by a spring 7 to engage the ratchet f andsaid rod 7* is provided between the arms 7'" with a collar f betweenwhich and the lower arm f is placed a spiral spring 7 which normallyserves to force the rod upwardly.

The rod f is provided at is upper end with a yoke g in which is pivotedan antifriction roller 9 and mounted on the top of the main frame andcentrally of the raised portion a thereof is a transverse shaft the endsof which project at both sides of the main frame, and at the left sideof the apparatus, said shaft is provided with a cam g which operates inconnection with the roller g to move the rod downwardly at eachrevolution of said shaft 9 The shaft is provided at the right side ofthe machine with a pulley g and mounted transversely of the rear endportion of the main frame and in the top thereof is a shaft whichcarries a cylindrical brush 9 and the shaft is provided at the rightside of the machine with a pulley g and mounted on he pulleys g and g isa belt h.

The shaft 9 is vertically adjustable, and this adjustment is efi'ectedby screws 7L2 at the opposite ends thereof and any suitable constructionto produce this result may be employed. The shaft 9 is also the maindrive shaft of the machine and is provided at the right side thereofwith a pulley 71/ and said shaft and the machine may be driven by a beltit operated by any suitable power device.

Mounted in the front and rear end portions of the main frame are beltconveyer rollers 2', and in the bottom portion of the main frame andslightly at the front and rear of the drums (Z are smaller belt conveyerguide rollers i and mounted on the rollers i and passing between therollers Z and drums (Z and beneath the rollers i is an endless or beltconveyer 2, preferably composed of strong heavy fabric material, andbeneath the drums (Z and between the rollers 2' in the constructionshown is placed a pan j, the bottom of which is preferably inclineddownwardly in the direction of the left side of the machine, and thispan is made in the form of a drawer, and may be inserted into positionby passing it through the left side of the main frame, as shown in Figs.1 and 3, and the front of said pan is provided with handles 7' and witha flexible discharge pipe j Mounted in front of the machine and provided, in the construction shown, with an independent support is afeeder m, consisting of a main outer barrel or casing m and asupplemental inner barrel or casing m between which is an annularchamber m The supplemental inner barrel or casing m projects through thefront end of the main barrel or casing m and is provided at the frontthereof with a hopper m, and mounted centrally in said supplementalinner easing m is a tubular shaft m provided with perforations m and aspiral conveyer web m and the front end of the shaft m projects and isprovided with a pulley m" on which is mounted a belt 71- whereby saidshaft may be turned, and the casing m is provided with a. hot water orsteam inlet pipe 02 and a discharge pipe 01 and a hot water or steampipe a extends into the front end of the shaft m, and said pipes areprovided with valves a.

The back or rear end of the inner conveyer casingm is provided with a.discharge chute 0 having a discharge opening 0 the dimensions of whichmay be regulated by an adjustable top plate or cover 0 With theforegoing description, the operation will be readily understood in viewof the following statement. The garbage or offal is fed into the feederm through the hopper m and the conveyer shaft m being set in operation,the said garbage or offal is fed through the feeder and discharged ontothebelt i and is carried by said belt between the rollers Z) and thedrums cl. During this operation hot water or steam is admitted throughthe pipes n and a and this aids in separating the liquids from thegarbage or offal, and especially is this true when said garbage or offalcontains an amount of grease. In the passage of the garbage or offalbetween the rollers band drums (Z, the liquids contained in said garbageor offal are extracted or separated therefrom and pass through the drums(Z, or the apertures and slots (Z and d therein and fall into the panand may be drawn off from said pan through the pipe j and said pan maybe removed and cleaned whenever desired.

The function of the brush g which is cylindrical in form is to clean theconveyer belt 2' or remove therefrom the garbage or offal after liquidshave been extracted therefrom, and in the above described operation, apart of the liquids extracted from the garbage or offal will passdownwardly around the drums (Z and, as will be seen, the operation ofthe rollers b and drums (Z is an in termittent operation, this resultbeing effected by means of the rod f, the ratchet f on the shaft 7, thepawl f and the cam g on the shaft 9 and this operation also facilitatesthe extraction of the liquids from the garbage or offal by reason of thefact that the said garbage or ofial remains longer under compression asit passes between the rollers Z) and drums (Z, but my invention is notlimited to this intermittent motion of the parts referred to, nor to theexact details of the construcion herein shown and described, and thefeeder m may be mounted in connection with the main frame, if desired,and other changes in and modifications of the construction herein shownand described may be made, within the scope of the appended claims,without departing from the spirit of my invention or sacrificing itsadvantages.
